I am new to this so pleas forgive me if something like this was already mentioned or resolved...
So I am mining ETH with two Redon 280x... All was going well, but the after resetting my PC I can not mine anymore, I get error (OpenCL error -4 (0) - cannot create DAG on GPU), however if I disconnect one card there are no errors... I have set virtual memory to 16 GB.
Can someone please help me, I can provide log files, I will run mine ETH for few days for you if you help me resolve this problem.
Which PSU, which OS, which driver version and which miner version are you using?
